i COMBINED PRESSER-FOOT AND CLAMP FOR HOLDING SEWING-MACHINEATTACHMENTS.,

SPECIFICATION forming part of Letters Patent No. 324,247, dated August11, 1885.

Applicant niedneccmberax, Issa. (Modem To @ZZ whom it may concern:

Be it known that4 I, FRANK L., GooDR-IOH, residing at Chicago, in thecounty of Cook and State of Illinois, and a citizen of the UnitedStates, have invented a new anduseful Improvement in a CombinedPresser-Foot and Clamp for Holding Sewing-Machine Attachments, of whichthe following is a full description, reference being had to theaccompanying drawings, in which- Figure-1 is a top or plan View; Fig. 2,a side elevation; Fig. 3, a rear elevation; Fig. 4, a front elevation;Fig. 5, a top or plan view of a hemmer and its attaching-arm; Fig. 6, asection on line :n x of Fig. 5; Fig. 7, a bottom View of a hemmerand-its attaching-arm; Fig. 8, a side elevation showing a modificationin applying the clamp; Fig. 9, asection through the clamp on line y y ofFig. 8.

The object of this invention is to construct a presser-foot forsewing-machines from a single piece of suitable metal, and therebydispense with the large portion of the labor heretofore required inmilling and finishing up presserfeet, and also to combine with suchpresserfoot a clamping device by which other attachments can be securedto the foot and held iirmly in position; and its nature consists informing a presser-foot from a single strip or bar of metal bent intoshape to form the shank or head and the foot proper, as hereinafter morespecically described, and in combining with such presser-foot a coactingpiece and a set-screw by which an arm or support carrying a hemmer orother attachment can be readily and quickly secured in place, ashereinafter more speciiically described,and pointed out in the claims.

In the drawings, A represents the head or portion which is attached tothe presser-bar, which head is formed by cutting out two circularrings,` a, in each of which is an opening, A', to receive the end of thepresser bar,

which rings are joined by a neck, a', leaving a space, A, between therings, as shown in Figs. 2 and 8. Ihe neck a has a screw-threadedopening to receive the stem of a setscrew, f, by which the device isfirmly clamped to the presser-bar, and when bent into shape the rings astand in parallel planes and at right angles to the neck a', as shown inFigs. 2 and 3.

B is the presser-foot, connected with the head A by a strip, B, whichstrip and the presser-foot B continue out from the lower ring, a, of thehead, as shown in Fig. 2, the piece forming the presser-foot being ofthe required width for the width of the foot. As shown in Figs. 1 to et,inclusive, the piece forming the presser-foot is turned at its forwardend and runs back on itself, and its inner end is turned at rightangles, as shown in Fig. 2, and this turned portion b b' forms a elainpfor holding other attachments. The necessary pressure for holdingpurposes is provided by a setscrew, e, the stem of which passes throughthe standard B', and enters a screw-threaded opening in the end or jaw bof the clamp, as

, shown in Fig. 2.

C is a plate-hemmer of the usual construction, attached tothe end of anarm or support, so as to properly coact with the presser-foot when inposition for use.

D is the arm or support, having its end D standing at right angles tothe main portion, as shown in Figs. 5 and 7, and this end D is bent soas to have two parts, d d', which stand at right angles, or nearly so,to each other; and this end D is slipped into the clamping device of thepresser-foot to have one portion, d, between the presser-foot and thepart b of the clamp, and its other portion, d, between the standard Band the end or jaw b of the clamp below the set-screw e, as shown inFig. 2, so that by drawing the clamp b b down by turning the set-screwthe parts d and d will be firmly clamped, holding the bar D and theattachment which it carries firmly in position.

The rings a, with the neck a', form a head for attachment to thepresser-bar through the set-screw f, and the presser-foot and itsstandard are formed from the same piece of metal,

and the blank from which these parts areA formed can be cut from theplate by means of a suitable die. It will also be seen that by turningthe portion which forms the presserfoot proper back on itself, as shownand described, a bite or clamp is likewise formed from the same piece ofmetal from which the head and foot are formed.

In use the presser-foot is secured to the bar by slipping the head A onthe bar and securing it by the set-screwf, and when the pressen foot isto be used alone this is all that is required; but when someotherattachment'is to IOC) be used in connection with the foot suchattachment has its arm or support D slipped into the clamp and lockedrml y by the setscrew e, and such attachment can be readily removed whenthrough With by simply loosening the set-screw and withdrawing the armor support from the clamp, leaving the presserfoot in condition for usewithout any other change.

Instead of forming the clamp from a continuation ofthe presserfoomsuchclamp might be made of an independent piece, as shown in Fig. S, inwhich case the portion b is shortened, and the portion b is providedwith side iianges, b", which clasp the standard B', as shown in Fig. 9,and form guides to keep the movable portion of the clamp in place. The

end D of the arm or support carrying the attachment is slipped intoplace in the clamp FRANK L. GOODRICI-L W'itnesses:
